PACKING CASE.

^ Application led November 12, 1921. Serial No. 514,537.

To all whom t may concern:

Be itknown that I, WALTER K. DEAN, a citizen of the United States,residing at Erie, in the county of Erie and State of Pennsylvania, haveinvented new and useful Improvements in a Packing Casefof which thefollowing is a specification.

The purpose of" this invention is to provide a packing case which may bereadily used for packing fragile articles, such as eggs, in such a waythat the willl pass through ordinary shipments an particularly in theparcels ost `without breakage. Preferably the case`1s such that theconstituent parts are collapsible so that the empty cases ma occupysmall space both forshipping an for stora e. In carrying out theinvention the co lapsible features, the strength of the receptacle, andthe cushioning eect of the pockets are all matters of considerationtogether with the cheapness of manufacture.

The invention is illustrated in the accompanying drawings as followsFig. 1 shows a perspective 'view of the case complete.- v

Figs. 2 and 3 plies of corrugated paper from which the outer case isformed.

1 marksthe louter shell. This is made of two plies of corrugatedpaper asshown in Figs. 2 and 3, thefpiece as shown in Fig. 2 being first woundinto the shape of theshell,

the folds being shown at a, b, c and d. The.

piece shown in Fig-3 is then wrapped over this first being supplied withadhesive material and preferably the folds are reversed so that thejoints are as completely broken as possible. The layers of paper 5 and 6are then secured to the inner and outer surfaces of these plies. y T'hismakes a very rigid construction, the paper preventing the flattening outof the corrugationsfand the reverse direction f the eorrugations givingrigidity in both directions. An inner shell has openings extendingthrough it and is assembled with the outer shell by lacinv it within theoutershell, the outer s ell c osing the openings in the inner shell andthe side walls ofthe inner shell closing the openings of the Both ofthese shellsA are collapsible so that they may be readily shipped emptyor stored. The pocket pieces 8 are formed .of partition strips 9 whichextend in' the .form of a zig zag in parallel diagonal llines and withreturn bends at the upper and lower edges of the pockets, the stripsbeing provided with f slits or notches 10 at v the crossings so as topermit theinterlapisvcollapsible as shown in Fig. 10. In the l smallerunit 1 the inner shell ordinarily is provided -with aplurality of thepocket4 pieces and the different pieces are separatedy y lseparatiplates 12 formed preferably of corrugate paper.

In the structureshown in Fig. 12 and following a larger unit is formed.In this the outer shell P corresponds to the shell 1 and the inner shell7B-corresponds to the shell 7. Thepocket piece 8a is made u with aplurality of rows'. This is forme by carrying the strips with aplurality of croing in each diagonal direction but the strips ave thereturn'bends at their upper and lower edges as in the construction shownin Fig.

6. The notching of the strips in order to provide them for a pluralityof rows of pockets is illustrated in Figs. 14, 15, 16 and 17 wherein areshown the strips 9a, 9b, 9c and 9d as formed prior to the assembling andwith the lines on which the bending at the top and bottom isaccomplished. The case is provided with a plurality of the pocket pieces8a and these are separated by the separating plates 12R. As willbe seenall the parts 1, 7a and 8a are collapsible so that these parts" may beput together and readily stored or shipped.

This provides a very rigid packing case so far as resisting crushingstrain 1s con-l cerned and at the same time there is suficient cushionineffect to save sucharticles as eggs from un ue breakage.

What I claim is new is:-

1. In a packing case, the combination of a container; and a pocket piececomprising a series of parallel zig zag shaped partition stripsextending diagonally across the container' with return bends at thecontainer walls, said strips crossing each other and being oppositelynotched and interlapped at the crossings.

2. In a packing case, the combination of a` container; and a pocketpiece comprising a series of parallel zig zag shaped partition stripsextending diagonally across the container with returif bends at thecontainer walls, said strips crossing each other and being oppositely`notched and interlapped at the crossings, said partition strips having aplurality of crossings in each direction and .forming a series of rowsor pockets.

3. In a packing case, the combination of a container; a plurality ofpocket pieces each comp-rising a series of parallel z ig zag shapedpartition strips extending diagonally across the container with returnbends at the container walls, said strips crossing.

eachother and being oppositely notched and interlapped at thecrossings;and separating plates between the pocket-pieces.

4. In a packing case, the combination of a container; and a pocket piececomprising a series of parallel zig zag shaped partition stripsextending diagonally across the container with return bends at thecontainer walls, said strips crossing each other and being oppositelynotched and interlapped at the crossings, said container and pocketpiece being collapsible.

5. In la packing case, the combination of` a container; and a pocketpiece comprising a series of parallel* zi zag'shaped partition stripsextending diagonally across the container with returnbends at thecontainer walls, saidA strips crossing eachother-and being oppositelynotched and interlapped at the crossings, said partition stripsv havinga plurality of crossin in each direction and lforming a series o ,rowsof pockets, said container and pocket piece being collapsible;

6. In a packing case, the combination of a container comprising twotelescoping shells open at their ends, one shell opening in a directionat right angles to the opening of the other when assembled.; and apocket piece within thel vcontainer comprising a series of parallel zigzag shaped partition strips extending diagonally across the containerwith return bends at the container walls, said strips crossing eachother and being oppositely notched `and interlapped at the crossings.

7. A container case formed of two plies ofcorrugated paper, each plybeing wound to form the shell and having its meeting edges extendingdiagonally across the shell and the corrugations of one shell being in adirection at an angle'to the corrugations of the other shell.

8. A container case formed of two plies of corrugated paper, each plybeing wound to form the shell and having its meeting edges extendingdiagonally across the shell and the corrugations of one shell being in adirection at an angle to the corrugations of' the other shell, thelioints between the edges of the two shells being broken.
